INTRODUCTION. Because of increasing number or cancers we are looking for new risk factors to choose groups for screening test. There is higher percent-age of cancers in patients with diabetes than in general population, specially after many years duration of the disease and in people treating by insulin. The aim of the study is analysis the frequency of occurrence of cancers in patients with diabetes, according to duration of the disease, treatment and dependence between carcinoma and diabetes diagnosis.
MATERIAL AND METHODS. The analysis was conducted in 1124 patients (mean age 62.96 ± 17.12 years, women - 51.3%; men - 48.7%) hospitalized in the Clinic in years 2004-2005. The occurrence of cancers and its types were estimated, this subgroup was compared with patients without cancers in the aspect of diabetes duration and treatment. The same time of diagnosis means time shorter than 12 months.
RESULTS. Cancers were diagnosed in 157 patients (13.96%), in women the most common was the cancer of the pancreas and of the colon (for 18.5%) and breast cancer (15.2%), and in men of the pancreas (20.0%), lung (15.4%), colon (10.8%) and prostate (9.2%). In the same time disease were diagnosed in 20.4% patients, first the diabetes in 60% and first cancer in 12%. In patients with diabetes and cancer comparing to patients only with diabetes were estimated: higher mean age (70.3 vs. 61.8 years), higher percentage of women (58.6% vs. 50.2%), shorter mean duration of the diabetes (8.43 vs. 9.35 years) and similar percentage of patients treating by insulin (62.8% and 61.9%).
CONCLUSIONS. Cancers are diagnosed more frequent in patients with diabetes than in general population. The most common in both sex is pancreatic cancer. The diagnosis of cancer in this group is independent on duration and treatment of diabetes.
